I want to use image management API independently without SMP, can you provide me example for the same?

[mksi]

I am developing an server app  on zephyr stack which requires to flash the image without SMP protocol, I receives the image data over BLE , how can I use Image management API to flash the zephyr.signed.bin image, any example code if you can provide ? Also, can I use flash_image.h API to flash the image directly?

Hello,

Sorry, the response I previously gave does not pertain to your issue, it was meant for a different one. I am deleting that response. Just letting you know that I have started looking into your issue and will get back to you soon.

Hello,

You can make use of the DFU Target library, see dfu_target_init() and dfu_target_write(). I looked into flash.h, and I believe the DFU Target API would be a better approach than using flash_img_buffered_write().

Kind regards,

Hi, Thanks for the reply.

As you mentioned DFU Target libray however it is not the part of Zephyr Stack hosted on public github  , it seems it is part of nrf SDK and I am not using nrf sdk. Pleas let me know if I can use this library without NRF SDK or any other alternative?

Hello,

Yes, you're right, the DFU target library isn't part of upstream Zephyr, it's specific to the nRF Connect SDK. So, you won't be able to use this library directly without using the Connect SDK.

We don't currently have a sample that matches your use case, but you might find more guidance by asking on the Zephyr Discord. You could look into using flash_img_buffered_write(), although I can't say for sure if it fits your scenario, as I haven’t used or worked with it myself.

Kind Regards,
